Abstract (en)
[origin: EP2458333A2] A road estimation device receives data including a core point (CPa, CPb) assigned along a road and assigned with an attribute for identifying the road. An input unit (13) inputs map data including links each having an attribute corresponding to the attribute of the core point (CPa, CPb). A search region set unit (17a, S220) sets a search region by using the core point (CPa, CPb) as a reference point. An extraction unit (17a, S250-S270) extracts a link included in the search region from the links of the inputted map data. An estimation unit (17a, S410-S450) estimates the road represented by the core point (CPa, CPb) according to an attribute of the extracted link and the attribute of the core point (CPa, CPb) on a map.
